1 Application filed February 14, 1883: (No model.)

To all whom it may concern:

Be it known that I, \V. HARRISON ALBAOI-l,

of hilansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Fruit-Evaporatms; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

7 My invention relates to an. improvement in fruit-eva-porators, theobject of the same being to provide a device of this character whichshall combine simplicity and economy in con struction with durabilityand efficiency in use; and with these ends in view my invention consistsin certain details in constructionv and combinations of parts, as willbe more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in front elevation ofmy improvement, showing the doors open. Fig. 2 is a longitudinalvertical sectional view of the same. Fig. 3 is a plan view of theheating chamber, and Fig. '4 represents a perspective view of theheating chamber with its sections discoir nected.

A represents an outer structure of any suitable size, and preferablyrectangular in shape, and having a slanting roof, which can be providedwith ventilators or not, as desired. This structure can be made ofanysuitable material, preferably wood, and is provided in front withdoors B, each of which latter is divided transversely, thereby formingtwo doors to the side, and enabling the lower doors to beopened withoutsubjecting the fruitchamber to cold drafts. This outer structure is madeslightly larger than the inner structure, so as .to form anair-spacebetween the fruit-chamber and hotair chamber and the buildingA, and the lower sections of the doors B are each provided with thesmall doors 0, which latter, when the doors B are closed, rest oppositethe door in the hotair chamber, so as to afford a passage-way to thedoors of the furnace without opening the large doors B. l

The inner structure consists of the fruitchamber I) and the hot-airchamber E, the latter being situated under the former and in directcommunication therewith. The fruitchamber Dis also preferablyrectangular in shape, and is made either of zinc or other sheet metal,covered or lined with asbestos,

thelieat generated in the furnace to the inner structure. Thisfruit-chamber can be formed with one or more compartments, each of whichis provided with the slides or flanges a, on which the trays rest, andeach tray is provided with a closed face, I), which latter, when all thetrays are in position, close the front of the fruit-chamber, therebypreventing the fruit in the trays from being exposed to the outsideatmosphere when the doors B are thrown open. The fruit-chamber l) isprovided with a top made of perforated metal or boards, and with abottom made of wire screen, which latter, besides being a uniformradiator of heat, also prevents any fruit from falling through into thehot-air chamber. The fruit-chamber is removably placed on the top of theheatingchamber, and is supported partly thereby and partly by thestandards (I, which latter are situated under the four corners of thefruitchamber. The heating-chamber E is made of detachable sheet-metalsections,which enables it to be taken apart for storage ortransportation. Each section is made of zinc or sheetiron,orothermetalcovered or lined'with asbestus, so as to retain the heattherein, and

like chamber is formed on which the fruitchamber rests. The object ofusing asbestus as a lining and covering for the heating-chamber isbecause of its indestructibility, the na thin layer will last a verylong time, thereby avoiding the inconvenience of a heavy thick coating,which would be the case if brick, cement, or similar material were used.I would not therefore have it understood that I lay claim to or desireto employ cement, fire-clay, or plaster-of-paris. Two of thesesectionseither the front and rear or the two sides-are provided withoutwardly-projecting tongues a, while the sides of the other twosections are flanged, so as to overlap the edges of the adjacentsections. The flanged sections are also provided with oblong slots i,adapted to register with the'tongues 'n of the adjacent sections. hen itis desired to secure the parts together, the tongues of one section arepassed both of which are non-conductors, and confine k when the partsare secured together a hopper-.

.ture of this mineral being such that a veryview.

.and then the last section is placed and secured in position, forming astrong and durable chamber, well adapted for the purpose in When it isdesired to take the chamber apart for storage or transportation, thetongues a are bent out straight and the parts separated without the useof any costly tools or skilled labor. One or more of the sections of thechamber are preferably provided with draft openings and regulators.

The fruit-chamber can also be made up of sections and secured togetherin a similar manner to the heating-chamber.

J is the furnace, of any suitable size and construction, situated in thehot-air chamber immediately under the fruit-chamber. This stove orfurnace restsup close to the front vertical wall, (I, which latter isprovided with a door which registers with the stove-door, and also withthe small doors 0 in the outer chamber.

The stove-pipe K passes through the wall of the hot-air chamber andthrough the outer structure, and then passes upward on the outside ofthe building, and is again connected therewith by the small pipe L,which latter is situated above the fruit-trays and serves to. ventilateboth structures.

To prevent dust or smoke from passing upward between the fruit-chamberand the outer structure, A, when the furnace-door is opened for thepurpose of adding fuel, I secure a partition, M, to the outer side ofthe hot-air chamber, above the furnace-door, and extend the same outwardto the walls of the outer chamber. This partition or roof, in connectionwith two vertical walls on opposite sides of the door, forms a box orpassageway, through which ingress is obtained to the furnace and egressfor the dust and smoke that passes through the stove-doors. The outerand inner structures can be slightly elevated on any suitable foundationhaving opening for the free entrance of air, or they can be providedwith draft-regulators, as desired. I prefer .to employ thedraft-regulators, as they enable me to better control the temperature ofthe evaporator, and obtain a more perfect ventilation without subjectingthe fruit to cold drafts. To illustrate, supposing the wind is blowingfrom the west, I would open the draft-regulator on the west side of theouter structure and on the east side of the hot-air chamber, all theotherdraft-openings being closed. This would necessitate the air makinga half circuit around the hot-ail" chamber, during which time itwouldbecome heated.

By making the heatingchamber and fruitchamber removable the outerstructure or building can be utilized for other purposes whenconvenient, and by making the chambers separable they can be packed insmall compass for storage and transportation.

These evaporators can be made for family use and of such size to be usedon an ordinary stove. In the latter instance a hot-air case .andfruit-chamber only would be employed.

Myimprovement is simple in construction, durable and effective in use,requires very little attention, and can be manufactured at a smallinitial cost.

' It is evident that slight changes in the construction and relativearrangement of the several parts might be resorted to without .departingfrom'the spirit of my invention, and hence I would have it understoodthat I do not limit myself to the exact construction of parts shown anddescribed, but consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a fruit-evaporator, the combination, with an outer structureprovided at its lower end with vertical corner posts, of aheatingchamber inclosing the furnace, and having its upper portionhopper-shaped and provided with flanges to rest upon said ,posts, and afruit-chamber having a wire-screen bottom extending over the hopperportion of the heating-chamber and adapted to be removably secured uponsaid chamber, substantially as set forth.

2. In a fruit-evaporator, a heating-chamber consisting of independentsections provided with slots near their corners and tongues projectingfrom their edges, said tongues being adapted to enter said slots and tobe bent, whereby the sections are secured together, substantially as setforth.

3. In a fruitevaporator, a heating-chamber consisting of independentsections, one of which is provided integrally with a passage, M, saidsections being each provided with slots and tongues, the latter beingadapted to enter the slots and be bent to secure thesecr tions together.

, 4. The combination, with an outer structure or'building and an innerfruit-chamber supported upon offsets from the frame of the building, ofthe hopper-shaped heating-chamber constructed substantially asdescribed, and lined or covered with asbestus, and situated under thefruit-chamber, and a stove or furnace located under the heatingchan1berand inclosed within the casing of the hopper, sub stantially as setforth.
